Abstract

The invention provides a lighting system and a control method thereof, which enables easy obtaining prescribed light source colors, and easy reproduce the prescribed light source colors. A lighting system according to embodiments includes a light element (22R, 22G, and 22B), a lighting circuit (104, 105, and 106), a remote control signal input unit (25 a), and a control circuit. Red, green and blue light sources lighting control circulation. The lighting circuits (104, 105, and 106) are instructed by a first signal inputed by a remote control signal receiving portion (25a), to start out lighting control of the lighting control circulation based on the red, green and blue light sources, and stops the lighting control circulation of the red, green and blue light sources according to the second signal inputted by the lighting circuits (104, 105, and 106).

Description

technical field [0001] Embodiments of the present invention relate to a lighting device and a control method thereof. Background technique [0002] In conventional color-changing LED lighting devices equipped with a plurality of light emitting diodes (Light Emitting Diodes, LEDs) with different light emitting colors, in order to change the color of the light source of the lighting device in a compact and simple manner, each light emitting diode is installed correspondingly and relative to the lighting. The light output of each light emitting diode is set by the rotation angle of the turntable provided rotatably by the apparatus main body, and each light emitting diode is turned on with the set light output. [0003] However, in the conventional color-changing LED lighting device, even if the required luminous color is set by the operation of the rotary table, it is still possible that the same luminous color as the desired luminous color cannot be obtained again after settin...
